STPSF: Simulated Point Spread Functions for the James Webb and Nancy Grace Roman Space Telescopes

https://github.com/spacetelescope/stpsf/blob/stable/docs/readme_fig.png?raw=true Badge showing current released PyPI version Github Actions CI Status https://codecov.io/gh/spacetelescope/stpsf/branch/master/graph/badge.svg https://zenodo.org/badge/DOI/10.5281/zenodo.15747364.svg https://img.shields.io/badge/ascl-1504.007-blue.svg?colorB=262255

STPSF HAS BEEN MIGRATED FROM WEBBPSF

STPSF produces simulated PSFs for the James Webb Space Telescope, NASA’s flagship infrared space telescope. STPSF can simulate images for any of the four science instruments plus the fine guidance sensor, including both direct imaging, coronagraphic, and spectroscopic modes.

STPSF also supports simulating PSFs for the upcoming Nancy Grace Roman Space Telescope (formerly WFIRST), including its Wide Field Instrument and a preliminary version of the Coronagraph Instrument.

Documentation can be found online at https://stpsf.readthedocs.io

STPSF requires input data for its simulations, including optical path difference (OPD) maps, filter transmission curves, and coronagraph Lyot mask shapes. These data files are not included in this source distribution. Please see the documentation to download the required data files.
